'Doomsday' comes true: the ocean is paralyzed, bringing the Earth back to the Ice Age?

The new study shows that climate change could cause ocean currents in the oceans to become numb, gradually turning the Northern Hemisphere region back to the Ice Age.

In the movie "The Day After Tomorrow" in 2004, the ocean flow stopped due to global warming. As a result, a series of disasters have happened to major cities in the world.

And experts believe that such a scary scenario can become a reality.

A recent study shows that climate change can cause ocean currents in the oceans to become numb, gradually turning the Northern Hemisphere region back to the Ice Age.

The phenomenon of climate change can cause ocean currents on the oceans to be paralyzed.

Previous studies have shown that the amount of carbon dioxide (CO ₂ ) in seawater will increase by twice (700ppm) by 2100. If the phenomenon continues, ocean currents can "collapse." " in 2400.

This conclusion was made by researchers at Scripps Institution of Oceanography at the University of California. Accordingly, they built a model to clarify the link between climate change and the possibility of paralyzing oceans.

Atlantic ocean currents, in which the warm and shallow currents move north (red), deeper, cooler currents move south (blue).

Specifically, the current climate model underestimates the potential impact on the Atlantic meridian convection (AMOC).

The weakening of ocean currents will cause the Northern Hemisphere region to drop its temperature suddenly, even returning to the Ice Age. If paralyzed ocean currents, ice melts in the Arctic, the Greenland area will carry a large amount of fresh water into the ocean. Meanwhile, AMOC needs a balance between fresh water and seawater.

Wei Liu, who led the study, said: "This study has clarified the impact of climate change on the oceans. Furthermore, the significance of the study also points to the consequences of climate change. regional and global ".

This study has clarified the impact of climate change on the oceans.

As a result of the study, the ocean currents will "collapse" 300 years after the amount of CO2 increases by 2. At this time, the North Atlantic surface temperature decreases by 2.4 degrees C and the temperature in the West Northern Europe plummeted - to 7 degrees C.
